Trying to book Paris to Basel SBB but gettingUnfortunately, the selected offer is not available"

[sarweins97]

I am getting the error: "

Unfortunately, the selected offer is not available. Please choose another product or contact Support"

I am booking a train from Paris Gare de Lyon at 12:22 next Sunday to Basel SBB. It was fine booking the train to Paris, but the way back is giving me this error. How can this be fixed?
